Description

Elektrische Schaltungsanordnung Electrical circuitry

Die Erfindung betrifft eine elektrische Schaltungsanordnung, umfassend eine eine elektrische Leiterbahnstruktur tragende Platine sowie ein oder mehrere elektrisch leitende und elektrisch leitend mit der Leiterbahnstruktur der Platine verbundene Stanzgitter.The invention relates to an electrical circuit arrangement, comprising a circuit board carrying an electrical conductor structure and one or more electrically conductive lead frames connected to the circuit structure of the circuit board.

Derartige elektrische Schaltungsanordnungen werden beispielsweise bei Kraftfahrzeugen zum Erstellen einer sogenannten Zentralelektrik eingesetzt. Bei der oben beschriebenen Schaltungsanordnung handelt es sich um eine Hybrid-Ausführung, bei der eine Leiterbahnen tragende Platine im elektrischen Verbund mit einem oder mit mehreren Stanzgittern steht.Such electrical circuit arrangements are used, for example, in motor vehicles to create a so-called central electrical system. The circuit arrangement described above is a hybrid version in which a circuit board carrying conductor tracks is in electrical connection with one or more lead frames.

Derartig ausgebildete Zentralelektriken werden eingesetzt, da infolge der größeren Querschnittsfläche der Stanzgitter, verglichen mit den Leiterbahnen der Platine, größere Ströme transportiert werden können. Daher er- folgt in aller Regel die Stromversorgung der Zentraielektrik über das oder die Stanzgitter, während sich die Steuerstromkreise auf der Platine befinden. Die Stanzgitter sind elektrisch mit Leiterbahnen der Platine verbunden. Beide Elemente - Platine und Stanzgitter - können Steckplätze aufweisen, um Relais, Sicherungen oder dergleichen anordnen zu können. Diese Steckplätze können durch Messerkontakte dargestellt sein, die vom Stanzgitter bzw. der Platine nach oben abragend angeordnet sind. Zum Herbeiführen der benötigten elektrischen Verbindung zwischen dem zumindest einen Stanzgitter und der Platine werden Lötverbindungen eingesetzt, die beispielsweise in einem Schwallbad erstellt werden. Zu diesem Zweck verfügt das zumindest eine Stanzgitter über Lötpins. Die auf diese Weise hergestellten elektrischen Verbindungen zwischen einem oder mehreren Stanzgittern und der Platine entsprechen den gewünschten Anforderungen. Jedoch ist es aufwendig, derartige elektrische Verbindungen herzustellen. Überdies sind automatisiert Lötverbindungen in wirt- schaftlicher Weise nur an solchen Gegenständen zu erstellen, die eine bestimmte Größe bzw. eine bestimmte Konfigurierung aufweisen. Aus diesem Grunde befinden sich bei vorbekannten Zentralelektriken die Platine und das oder die Stanzgitter in einem schichtigen Aufbau zueinander. Solche Zentralelektriken sind beispielsweise bekannt geworden aus DE 42 44 046 C2 und DE 197 13 008 C1. Ferner ist bei einer unterschiedlichen Ausstattung von Zentralelektriken bei Kraftfahrzeugen das Handling der Einzelteile aufwendig; insbesondere müssen bei einer Montage am Band einem Monteur bei unterschiedlicher Ausstattung des Kraftfahrzeuges unterschiedliche komplette Zentralelektriken zur Verfügung stehen.Central electrical systems designed in this way are used because, owing to the larger cross-sectional area of the lead frames, larger currents can be transported compared to the conductor tracks of the circuit board. For this reason, the central electrical system is usually supplied with power via the lead frame (s) while the control circuits are on the circuit board. The lead frames are electrically connected to the circuit board's conductor tracks. Both elements - circuit board and lead frame - can have slots in order to be able to arrange relays, fuses or the like. These slots can be represented by knife contacts, which protrude upwards from the lead frame or the circuit board. To produce the required electrical connection between the at least one lead frame and the circuit board, solder connections are used, which are created, for example, in a wave bath. For this purpose, at least one lead frame has solder pins. The electrical connections made in this way between one or more lead frames and the circuit board meet the desired requirements. However, it is expensive to make such electrical connections. In addition, automated soldered connections can only be made economically on objects that have a certain size or configuration. For this reason, the board and the lead frame or lead frames are in a layered structure to each other in prior art central electronics. Such central electrical systems have become known, for example, from DE 42 44 046 C2 and DE 197 13 008 C1. Furthermore, with different configurations of central electronics in motor vehicles, the handling of the individual parts is complex; in particular, when assembling on the assembly line, a mechanic with different equipment of the motor vehicle must have different complete central electronics available.

Daher liegt der Erfindung die Aufgabe zugrunde, eine elektrische Schaltungsanordnung, insbesondere geeignet zum Ausbilden einer Zentral- elektrik für ein Kraftfahrzeug, dergestalt weiterzubilden, dass die zu dem vorbekannten Stand der Technik aufgezeigten Nachteile vermieden sind.The invention is therefore based on the object of developing an electrical circuit arrangement, in particular suitable for forming a central electrical system for a motor vehicle, in such a way that the disadvantages indicated in relation to the prior art are avoided.

Diese Aufgabe wird erfindungsgemäß zum einen dadurch gelöst, dass das zumindest eine Stanzgitter zum elektrischen Verbinden desselben mit ei- ner Leiterbahn der Platine über zumindest ein Steckkontaktelement und die Platine über ein mit dem zumindest einen Steckkontaktelement des Stanzgitters zusammenwirkendes Steckkontaktelement verfügt.This object is achieved, on the one hand, in that the at least one lead frame for electrically connecting it to a conductor track of the board has at least one plug contact element and the board has a plug contact element which interacts with the at least one plug contact element of the lead frame.

Ferner wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass sowohl das zumindest eine Stanzgitter als auch die Platine zum elektrischen Verbinden dieser beiden Elemente miteinander über jeweils zumindest ein Steckkontaktelement verfügen und diese Steckkontaktelemente miteinander durch ein elektrisches, mit diesen Steckkontaktelementen zusammenwirkendes Steckverbindungselement verbunden sind.Furthermore, this object is achieved according to the invention in that both the at least one lead frame and the circuit board for electrically connecting these two elements to one another each have at least one plug contact element and these plug contact elements are connected to one another by an electrical plug connector element which interacts with these plug contact elements.

Bei einer solchen elektrischen Schaltungsanordnung ist das zumindest eine Stanzgitter mit der Platine über steckerartig in Eingriff stellbare Kontaktelemente verbunden. Gemäß dem ersten Lösungsvorschlag verfügen zu diesem Zweck sowohl das Stanzgitter als auch die Platine über jeweils komplementär zusammenwirkende Steckkontaktelemente. Bei diesen Steckkontaktelementen kann es sich beispielsweise um steckerförmige Steckkontaktelemente, zweckmäßigerweise dem Stanzgitter zugeordnet, und um buchsenartige Steckkontaktelemente, zweckmäßigerweise der Platine zugeordnet, handeln. Eine elektrische Kontaktierung zwischen ei- nem Stanzgitter und der Platine wird somit durch Verbinden von zwei komplementär ausgebildeten Steckkontaktelementen erreicht. Ein Fügen ist beim Gegenstand dieser Schaltungsanordnung grundsätzlich nicht erforderlich. Die Vorteile einer solchen Schaltungsanordnung betreffen ins- besondere die Möglichkeiten der Ausgestaltung derselben, da deren Ausgestaltung nunmehr nicht durch fügeverfahrenbestimmte Faktoren beschränkt ist. Beispielsweise können bei der beanspruchten Schaltungsanordnung die Platine und das zumindest eine Stanzgitter im wesentlichen auch in einer Ebene zueinander befindlich angeordnet sein. Ebenfalls ist es möglich, mehrere Platinen durch Stanzgitter miteinander zu verbinden, um beispielsweise auf diese Weise größere Schaltungsanordnungen oder auch bezüglich ihrer Konfigurierung kompliziert aufgebaute Schaltungsanordnungen zu realisieren. Denkbar ist ebenfalls die Anordnung eines oder mehrerer Stanzgitter, die in sich eine Abkantung aufweisen, um auf diese Art und Weise zwei oder mehrere Platinen winklig zueinander anzuordnen. In dieser Ausgestaltung ist eine Raumausfüllung bei gleichzeitiger Zugänglichkeit der Platinen und insbesondere der Steckplätze möglich.In such an electrical circuit arrangement, the at least one lead frame is connected to the circuit board via contact elements which can be engaged in a plug-like manner. According to the first proposed solution, both the lead frame and the circuit board each have complementary interacting plug contact elements for this purpose. These plug contact elements can, for example, be plug-shaped plug contact elements, expediently assigned to the lead frame, and socket-like plug contact elements, expediently assigned to the circuit board. Electrical contact between a lead frame and the circuit board is thus achieved by connecting two complementary plug contact elements. A joining is basically not necessary with the subject of this circuit arrangement. The advantages of such a circuit arrangement concern in particular the possibilities of designing the same, since their design is now not limited by factors determined by the joining method. For example, in the circuit arrangement claimed, the circuit board and the at least one lead frame can also be arranged essentially in one plane to one another. It is also possible to connect a plurality of circuit boards to one another by means of leadframes, in order in this way, for example, to implement larger circuit arrangements or also circuit arrangements with a complicated structure. It is also conceivable to arrange one or more lead frames, which have an edge in them, in order to arrange two or more boards at an angle to one another in this way. In this embodiment, space can be filled while the boards and, in particular, the slots are accessible.

Gemäß dem weiteren Lösungsvorschlag verfügen ebenfalls die beiden Elemente - Stanzgitter und Platine - über Steckkontaktelemente. Diese sind zum Herbeiführen der gewünschten elektrischen Verbindung zwischen dem Stanzgitter und der Platine nicht unmittelbar in Eingriff stellbar. Eine elektrische Verbindung zwischen zwei solchen Kontaktelementen erfolgt durch Einsatz eines elektrischen Steckverbindungselementes. Dieses Steckverbindungselement wirkt zusammen mit den Steckkontaktelementen der Platine und des Stanzgitters. Ein solches Steckverbindungselement kann ein reines Verbindungselement sein. Dieses Steckverbindungselement kann jedoch auch ein Funktionselement sein, beispielswei- se eine Sicherung oder dergleichen. Auf diese Weise kann grundsätzlich die Platine durch das Stanzgitter kontaktiert werden, ohne dass das Stanzgitter unmittelbar mit der Platine in Verbindung gestellt sein muß.According to the further proposed solution, the two elements - lead frame and circuit board - also have plug contact elements. These cannot be directly engaged to bring about the desired electrical connection between the lead frame and the circuit board. An electrical connection between two such contact elements is made by using an electrical connector element. This connector element works together with the plug contact elements of the circuit board and the lead frame. Such a connector element can be a pure connector element. However, this plug connection element can also be a functional element, for example a fuse or the like. In this way, the circuit board can in principle be contacted by the lead frame without the lead frame having to be connected directly to the circuit board.

Der im Rahmen dieser Ausführungen benutzte Begriff „Steckkontakt- element" umfaßt sämtliche Elemente, mit denen durch mechanisches in Eingriffstellen miteinander eine elektrische Verbindung zwischen solchen Elementen herstellbar ist. Somit umfaßt dieser Begriff sowohl steckerför- mige Steckkontaktelemente im eigentlichen Wortsinne, die mehrfach zusammengesteckt und gelöst werden können. Dieser Begriff umfaßt jedoch auch solche Ausgestaltungen, bei denen zunächst nur das einmalige Erstellen einer elektrischen Verbindung im Vordergrund steht. Bei diesen Kontaktelementen handelt es sich um sogenannte Einpreßkontakte, deren Steckerteile sich beim Einbringen derselben in komplementär ausgebildete Buchsenteile plastisch unter Zurückbehaltung einer Restrelaxation verfor- men.The term “plug-in contact element” used in the context of these explanations includes all elements with which an electrical connection between such elements can be established by means of mechanical points of engagement with one another. Thus, this term encompasses both plug-shaped plug-in contact elements in the actual sense of the word, which are plugged together and disconnected several times However, this term also encompasses those configurations in which initially only the one-off creation of an electrical connection is in the foreground. These contact elements are so-called press-in contacts, the plug parts of which are complementarily designed when they are introduced Plastic parts of the socket are deformed while retaining a residual relaxation.

Ein Steckkontaktelement des Stanzgitters ist in einer bevorzugten Aus- gestaltung durch eine Abkantung eines Fortsatzes aus der Ebene des Stanzgitters gebildet. Dabei ist vorgesehen, dass die Kontur des Steckkontaktelementes bereits durch den Stanzvorgang gebildet wird. Die Abkantung erfolgt, damit bei einer bezüglich ihrer Ebene parallelen Anordnung von Stanzgitter und Platine eine Kontaktierung der beiden Elemente miteinander möglich ist.In a preferred embodiment, a plug contact element of the lead frame is formed by folding an extension from the plane of the lead frame. It is provided that the contour of the plug contact element is already formed by the stamping process. The folding takes place so that a contact of the two elements with one another is possible with a parallel arrangement of the lead frame and blank with respect to their plane.

Zur Kontaktierung des zumindest einen Stanzgitters an einer Platine können ebenfalls als Steckkontaktelement die ansonsten ggf. zur Bereitstellung der Steckplätze eingesetzten Messerkontaktverbindungen dienen. Beispielsweise kann eine Platine zum Kontaktieren eines Stanzgitters einen solchen Messeraufnahmekontakt aufweisen. Das zu diesem Messeraufnahmekontakt komplementäre messerartige Steckkontaktelement des Stanzgitters ist ein Fortsatz des Stanzgitters, der in die Messeröffnung des Messeraufnahmekontaktes eingreift. Auch dieser Fortsatz ist zweckmäßi- gerweise Teil des Stanzgitters.For contacting the at least one lead frame on a circuit board, the blade contact connections that are otherwise used to provide the slots can also serve as the plug contact element. For example, a circuit board for contacting a lead frame can have such a knife receiving contact. The knife-like plug contact element of the lead frame, which is complementary to this knife receiving contact, is an extension of the lead frame which engages in the knife opening of the knife receiving contact. This extension is also expediently part of the lead frame.

Grundsätzlich kann ebenfalls vorgesehen sein, die Steckkontaktelemente des Stanzgitters durch Punktschweißen, Nieten oder dergleichen an dem Stanzgitter zu befestigen.In principle, it can also be provided to fasten the plug contact elements of the lead frame to the lead frame by spot welding, riveting or the like.

Durch die Möglichkeit des Erstellens der benötigten elektrischen Verbindungen allein durch Zusammenstecken der jeweiligen Steckkontaktelemente können, beispielsweise bei einer Ausrüstung von Kraftfahrzeugen mit unterschiedlichen Zentralelektriken diese bei der Montage am Band unmittelbar im Kraftfahrzeug unterschiedlich ausgerüstet werden. Beispielsweise können bei unterschiedlicher Ausrüstung unterschiedliche Stanzgitter mit einer Platine zusammengesteckt werden. Ein solches Zusammenstecken der beiden Elemente, bei denen die elektrische Verbindung zwischen beiden hergestellt wird, erfolgt zweckmäßigerweise auf einem Träger, der bevorzugt Teil eines Gehäuses für eine solche Zentralelektrik darstellt. Dieser Träger bzw. das Gehäuse verfügt über Montagecodierungen, damit sowohl die zumindest eine Platine als auch das zumindest eine Stanzgitter lagerichtig zueinander angeordnet und elektrisch miteinander verbunden werden können. Dabei ist vorgesehen, dass die eingesetzten Elemente - Platine sowie Stanzgitter - jeweils von dem Träger und/oder dem Gehäuse unterstützt bzw. gehalten werden.The possibility of establishing the required electrical connections simply by plugging the respective plug-in contact elements together, for example when equipping motor vehicles with different central electrical systems, can equip them differently directly on the assembly line in the motor vehicle. For example, with different equipment, different lead frames can be plugged together with a circuit board. Such a plugging together of the two elements, in which the electrical connection between the two is established, is expediently carried out on a carrier, which is preferably part of a housing for such a central electrical system. This carrier or the housing has assembly codes so that both the at least one circuit board and the at least one lead frame are arranged in the correct position relative to one another and are electrical can be connected to each other. It is provided that the elements used - board and lead frame - are each supported or held by the carrier and / or the housing.

Vorteilhaft ist bei der beanspruchten Schaltungsanordnung ferner, dass die aus dem zumindest einen Stanzgitter und der zumindest einen Platine gebildete Schaltungsanordnung nachträglich umgerüstet werden kann.It is also advantageous in the circuit arrangement claimed that the circuit arrangement formed from the at least one lead frame and the at least one circuit board can be retrofitted.

Teil einer Zentralelektrik für ein Kraftfahrzeug ist eine Platine 1 mit einer auf der Unterseite der Platine 1 befindlichen Leiterbahnstruktur. Die Platine 1 ist zur Bereitstellung von Steckplätzen mit nach oben abragenden Messeraufnahmekontakten M ausgerüstet. Die Messeraufnahmekontakte M dienen zur elektrischen Kontaktierung von Relais, Sicherungen und anderen elektrischen/elektronischen Elementen. Die Platine 1 verfügt ferner über Einpresskontaktbuchsen. Derartige Einpresskontaktbuchsen sind weiter unten näher zur Figur 3 beschrieben. Die Einpresskontaktbuchsen dienen zum elektrischen Kontaktieren von Leiterbahnen der Platine 1. Figur 2 zeigt ein Stanzgitter 2, welches aus einem elektrisch leitenden Metall besteht. Das Stanzgitter 2 dient unter anderem zur Kontaktierung von Leiterbahnen der Platine 1. Ferner trägt auch das Stanzgitter 2 Messeraufnahmekontakte M. Einige Messeraufnahmekontakte M der Platine 1 sowie des Stanzgitters 2 sind in der montierten Stellung der beiden Elemente - Platine 1 und Stanzgitter 2 - parallel zueinander liegend angeordnet, so dass bestimmte Bauelemente sich sowohl in Messeraufnahem- kontakten M der Platine 1 als auch in Messeraufnahmekontakten M des Stanzgitters 2 abstützen können. Zum elektrischen Kontaktieren von Lei- terbahnen der Platine 1 verfügt das Stanzgitter 2 über mehrere stecker- förmige Steckkontakte S, die bei dem dargestellten Ausführungsbeispiel als Einpreßkontakte ausgebildet sind. Bei dem dargestellten Ausführungsbeispiel sind die steckerförmigen Steckkontakte S jeweils als Doppelsteckerkontakte konzipiert. Jedes steckerförmige Steckkontakt S greift ein in eine aus zwei Einpresskontaktbuchsen gebildete Kontaktbuchsenanordnung der Platine 1.Part of a central electrical system for a motor vehicle is a circuit board 1 with a conductor track structure located on the underside of the circuit board 1. The circuit board 1 is equipped with knife receptacle contacts M which protrude upwards in order to provide slots. The knife receiving contacts M are used for electrical contacting of relays, fuses and other electrical / electronic elements. The board 1 also has press-fit contact sockets. Such press-in contact sockets are described in more detail below in relation to FIG. 3. The press-in contact sockets are used to make electrical contact with the conductor tracks of the circuit board 1. Figure 2 shows a lead frame 2, which consists of an electrically conductive metal. The lead frame 2 is used, among other things, for contacting conductor tracks of the circuit board 1. Furthermore, the lead frame 2 also carries knife receiving contacts M. Some knife receiving contacts M of the circuit board 1 and the lead frame 2 are parallel to one another in the assembled position of the two elements - circuit board 1 and lead frame 2 arranged horizontally, so that certain components can be supported both in knife receiving contacts M of the circuit board 1 and in knife receiving contacts M of the lead frame 2. For the electrical contacting of conductor tracks of the circuit board 1, the lead frame 2 has a plurality of plug-shaped plug contacts S, which in the exemplary embodiment shown are designed as press-in contacts. In the exemplary embodiment shown, the plug-shaped plug contacts S are each designed as double plug contacts. Each plug-shaped plug contact S engages in a contact socket arrangement of the circuit board 1 formed from two press-in contact sockets.

In Figur 3 ist die bei dem dargestellten Ausführungsbeispiel vorgesehene Kontaktierung zwischen einem steckerförmigen Steckkontakt des Stanz- gittere 2 und einer Kontaktbuchsenanordnung 3 der Platine 1 dargestellt. Der in Figur 3 dargestellte, als Doppelstecker steckerförmige Steckkontakte ausgebildete steckerförmige Steckkontakt S ist ein Fortsatz des Stanzgitters 2 und in seinem Endbereich gegenüber der Ebene des Stanzgitters 2 zur Platine 1 hin um etwa 90° nach unten abgekantet (vgl. Figur 2). Zur tatsächlichen Kontaktierung einer Leiterbahn L der Platine 1 dienen zwei Steckerfortsätze 4, 5 des steckerförmigen Steckkontaktelements S des Stanzgitters 2. Die Steckerfortsätze 4, 5 sind durch ihre öse- nartige Ausbildung in Querrichtung zur Steckrichtung materialelatisch ausgebildet, so dass diese unter einer gewissen Vorspannung stehend an der Innenseite der die Kontaktbuchsenanordnung 3 bildenden Einpresskontaktbuchsen 6, 7 gebildeten Innenwand anliegend. Die Einpresskontaktbuchsen 6, 7 sind innenseitig elektrisch leitend ausgebildet, wobei dieses Material mit der Leiterbahn L in Verbindung steht. Die Kontaktierung zwischen dem Stanzgitter 2 und der Platine 1 kann somit als Einpresskontak- tierung angesprochen werden. Mit einer, wie in Figur 3 beschriebenen Kontaktierung können größere Ströme an die Leiterbahn L der Platine 1 übertragen werden. Figur 4 zeigt eine weitere Möglichkeit einer elektrischen Verbindung eines Stanzgitters 2' mit einer Platine 1'. Zu diesem Zweck verfügt die Platine 1' über dieser Verbindung dienende Messeraufnahmekontakte, in die ein von einem Fortsatz 9 des Stanzgitters 2' gebildeter messerartiges Steckkon- taktelement eingeführt ist. Somit handelt es sich bei diesen Kontaktelementen ebenfalls um Steckkontaktelemente, die alleinig durch Zusammenführen elektrisch miteinander in Verbindung gebracht werden können.FIG. 3 shows the contacting provided in the illustrated embodiment between a plug-type plug contact of the lead frame 2 and a contact socket arrangement 3 of the circuit board 1. The plug-shaped plug-in contact S shown in FIG. 3 and in the form of a double plug is a continuation of the lead frame 2 and, in its end region opposite the plane of the lead frame 2 to the board 1, is bent downward by approximately 90 ° (see FIG. 2). Two plug extensions 4, 5 of the plug-shaped plug contact element S of the lead frame 2 are used for the actual contacting of a conductor track L of the circuit board 1. The plug extensions 4, 5 are materially formed by their eye-like design in the transverse direction to the plug direction, so that they are under a certain prestress abutting the inside of the press-in contact bushes 6, 7 forming the contact socket arrangement 3. The press-in contact sockets 6, 7 are electrically conductive on the inside, this material being connected to the conductor track L. The contact between the lead frame 2 and the circuit board 1 can thus be addressed as press-in contact. With a contact, as described in FIG. 3, larger currents can be transmitted to the conductor track L of the circuit board 1. FIG. 4 shows a further possibility of electrically connecting a lead frame 2 'to a circuit board 1'. For this purpose, the circuit board 1 'has knife receiving contacts serving this connection, into which a knife-like plug contact element formed by an extension 9 of the lead frame 2' is inserted. Thus, these contact elements are also plug-in contact elements that can be electrically connected to one another only by merging.

Das mit der Platine 1 verbundene Stanzgitter 2 ist - wie in Figur 5 gezeigt - in ein Gehäuse 10 eingesetzt. In Figur 5 ist lediglich der untere, trägerartig ausgebildete Bereich des Gehäuses 10 gezeigt. Zum Bestücken des Gehäuses 10 ist zunächst die Platine 1 auf den trägerartigen Boden des Gehäuses 10 eingesetzt worden. Zur lagerichtigen Montage der Platine 1 dienen Codeecken 11 , von denen zwei mit diesem Bezugszeichen in Figur 5 kenntlich gemacht sind. Die Platine 1 ist unterseitig von dem Gehäuse 10 unterstützt. In einem nächsten Montageschritt ist das Stanzgitter 2 in das Gehäuse 10 eingesetzt worden. Am Gehäuse 10 angeordnete Codierungszapfen 12 dienen dem Zweck, das Stanzgitter 2 lagerichtig einzusetzen. Diese durchgreifen entsprechende Öffnungen in dem Stanzgitter 2. Bei diesem Montageschritt erfolgt eine elektrische Kontaktierung zwischen dem Stanzgitter 2 und Leiterbahnen der Platine 1 durch Einführen der als Doppelstecker ausgebildeten steckerförmigen Steckkontakte S in die Kontaktbuchsenanordnungen der Platine 1.The lead frame 2 connected to the circuit board 1 is inserted into a housing 10, as shown in FIG. In Figure 5, only the lower, carrier-like area of the housing 10 is shown. To populate the housing 10, the circuit board 1 has first been inserted onto the carrier-like bottom of the housing 10. Code corners 11, two of which are identified by this reference number in FIG. 5, are used for the correct mounting of the circuit board 1. The circuit board 1 is supported on the underside by the housing 10. In a next assembly step, the lead frame 2 was inserted into the housing 10. Coding pins 12 arranged on the housing 10 serve the purpose of using the lead frame 2 in the correct position. These pass through corresponding openings in the lead frame 2. In this assembly step, electrical contact is made between the lead frame 2 and the conductor tracks of the circuit board 1 by inserting the plug-shaped plug contacts S designed as a double plug into the contact socket arrangements of the circuit board 1.

In Abhängigkeit von der gewünschten Ausrüstung der zu erstellenden Zentralelektrik können in diesem Schritt auch unterschiedliche Stanzgitter montiert werden. Ferner besteht die Möglichkeit, in einer weiteren Ebene oberhalb des Stanzgitters 2 weitere Stanzgitter anzuordnen und die Platine 1 und/oder das Stanzgitter 2 auf entsprechende Weise zu kontaktieren, wie dies anhand der elektrischen Kontaktierung zwischen dem Stanzgitter 2 und der Platine 1 beschrieben ist. BezugszeichenlisteDepending on the desired equipment of the central electrical system to be created, different lead frames can also be installed in this step. Furthermore, there is the possibility of arranging further lead frames in a further plane above the lead frame 2 and to contact the circuit board 1 and / or the lead frame 2 in a corresponding manner, as is described on the basis of the electrical contact between the lead frame 2 and the circuit board 1.
